2Introduction of Centrifugal Fan Blower
- Centrifugal Fans and Blowers typically have one
of eight types of wheels that draw the air into
the inlet of the blower housing, through the
wheel, and discharges it at 90 degrees . - The two most common types of Centrifugal
Blowers are Pressure Blowers and Volume Blowers. - Pressure Blowers are designed to draw or push air
at high pressures, rated in static pressure water
gauge (SPWG). Volume Blowers are designed to draw
or push larger volumes of air, rated in cubic
feet of air per minute (CFM),at lower static
pressures than Pressure Blowers.

5Principles of Centrifugal Fan
The centrifugal fan uses the centrifugal power
supplied from the rotation of impellers to
increase the kinetic energy of air/gases. When
the impellers rotate, the gas particles near the
impellers are thrown off from the impellers, then
move into the fan casing. As a result, the
kinetic energy of gas is measured as pressure
because of the system resistance offered by the
casing and duct. The gas is then guided to the
exit via outlet ducts.
